MILWAUKEE -- The last out had been recorded, and as his teammates grabbed their equipment and headed back to the clubhouse, D-backs outfielder Ketel Marte leaned on the dugout railing and stared out on the emptying field, a plastic Gatorade bottle in his hand.

The D-backs had just fallen, 2-0, to the Brewers, their 17th straight road loss, and Marte wasn't ready to let it go just yet.

Finally, he stood, fired the bottle to the ground and departed the dugout.

"Very frustrating," Marte said. "We’re losing a lot of games. It’s something pretty incredible. All we can do is work on the small things, each and every one of us. Work on the small things."

There have been times during this dismal stretch that the D-backs have given away games or played poorly. Sunday, though, they were simply beaten by one the game's best pitchers in Corbin Burnes.

The right-hander was on top of his game, striking out a career-high 13 without allowing a walk over seven innings.

On consecutive nights, the D-backs had to face Freddy Peralta, Brandon Woodruff and Burnes. Not a trio you want to go up against when you're starving for a win.

"They've got some good starting pitching," D-backs manager Torey Lovullo said. "We know that. We knew that walking in here, and I think that's a lot of their identity. They also have some very good position players that bang the baseball around. But I think the pitching is their carry tool, and it's helping them get to where they want to get to each and every night."

The D-backs did get a good start out of Caleb Smith, who allowed one run -- a homer by Daniel Robertson in the fifth -- over five innings while striking out eight.

Smith (2-2) opened the year in the rotation before being sent to the bullpen after his first start of the season. He pitched well enough in the ‘pen to get the D-backs to shift him back to starting.

"I thought Caleb Smith was really good for the first three innings," Brewers manager Craig Counsell said. "He was making pitches. He was dotting the inside corner really, really well on us. In the fourth inning, we had a chance and didn't cash in, then [Robertson] did in the fifth. It's how you're consistent. We didn't put a big number on the board today, but we got a great pitching performance and a guy, [Robertson], who hasn't played much lately, steps up with a big homer."

On the flip side, when a team is going badly like the D-backs are right now, that's how you lose, when a guy who has been struggling comes up with a big homer.

"We're slowly doing things right, but we're not doing everything right because we're not winning baseball games," Lovullo said. "So we'll continue to work on all those things."

First, though, the D-backs will take Monday off before opening a brief two-game set against the A's in Oakland.

The rest may do them some good. Since the first road loss in this current streak back on May 4, the D-backs have had just one off-day.

"It's been a lot of baseball games," Lovullo said. "And for us to get away and just recharge our batteries and just take a breather, I believe in balance. At some point tomorrow night, just kick those gears back in and get ready to wake up the following morning to play your best baseball game on Tuesday."
